Abstract (en)

[origin: WO2022162228A1] Methods, systems, and Instructions are disclosed to support restricted Proximity-based Services (ProSe) direct discovery in a wireless network. In one embodiment, a method is performed by a first network function (NF), where a terminal device communicates with another terminal device based on the restricted ProSe direct discovery. The wireless network is to assign one ProSe Discovery user equipment (UE) identifier (PDUID) to the terminal device to identify the terminal device in the restricted ProSe direct discovery. The method comprises receiving (602) a request message including a UE identifier (UE ID), where the UE ID uniquely identifies the UE in the wireless network; generating (604) a ProSe Discovery user equipment (UE) identifier (PDUID) for the UE ID based on the UE ID; and transmitting (606) a PDUID information message to a second NF, where the PDUID information message comprises the PDUID and a validity timer.
